An automatic solenoid dump valve should be set to trip if the evaporator produces distillate with salt content exceeding ______.

🔍 Key Concepts

• Distillate purity requirements for potable (drinking) water made by an evaporator • Relationship between grains per gallon (gpg) and how "salty" or "fresh" the water will taste and behave in boilers • Purpose of an automatic solenoid dump valve in protecting systems that use the distillate

💭 Think About

• Think about whether this distillate is intended to be used as potable water, boiler feedwater, or both—how pure does it need to be? • Which of the listed salt contents would most likely be considered too salty for high‑quality distillate, triggering an automatic dump rather than sending it to the tank? • Compare the options: which value looks like a reasonable upper limit for salt content before you would want to reject the water to protect equipment and crew health?

✅ Before You Answer

• Verify which gpg range is typically accepted for potable/boiler distillate on ships—very low salt, not just "a little less than seawater". • Check that you understand that a lower trip setting (smaller gpg number) means stricter purity—the valve dumps sooner. • Confirm that the option you pick would reasonably protect both human consumption and machinery rather than just being barely better than seawater.
